TUBING- OIL SAVER.

Application filed December--13, 1821.

Be it known that I, OLIVER A. Knannn, a citizen of the United States ofAmerica, residing at Bartlesville, in Washington County, State of-Oklahoma,have invented a new and useful Improvement in Tubing OilSavers.

' This invention is for the purpose of saw ing the oil in the tubingof-an oil well when it is necessary to pull the tubing to clean out .thewell, or for any other reason; and also to carry off such oil or anyrefuse in the tubing, when the same is pulled, and dispose of the samesothat it will not interfere with the progress of the work.

hen it is necessary to pull the tubing generally full of fluid. Thetubing is raised until a connection between joints is reached, when thetop joint is unscrewed from the lower. The fluid in the upperjoint thencommonly runs out on the ground or floor, wasting the oil, it the tubingis full of oil, and permitting the fiuid'to run over the derrick floor,greatly hamperingthe workmen in theirwork.

My invention consists of two half-cylindrical shaped sides; each sidehasa lock-arm and a hinge-arm; the hinge-arms are hinged on a hinge-boltattached by means of a clamp or saddle to the gas pipe in the casinghead. The hinge-bolt has an offset bend and a collar with a set screw ata convenient point on which the hingearms rest. The top and bottominside edges, where they fit around the tubing, and the inside edges ofthe sides, where they come together, are fitted with packing, leavingacircular hole in the center for the tubing. The sides are larger indiameter at the bottom than at'the top, to allow for the bottomsettingover the collar of the lower joint of tubing. One of the sides has aspout near the bottom for hose attachment. One of the lock-arms has ahook on the bottom in which is adjusted a lock-link with a handle, whichis used to fasten the lock-arms and sides together when adjusted aroundthe tubing. On the outside of the lock-arms is a wedge-boss tofacilitate the locking of the sides together when adjusted around thetubing. When the oil saver is adjusted around the tubing,

collar upper part around the upper oint, the peer.

ing fits'closely together around the tubing at the top and bottom. andcomes together along the edges, making a cavity between the tubing andthe sides of the oil saver, to take care of the fluid inthe upper jointof tubing as it is being unscrewed, and when the upper joint of tubingis unscrewed the fluid runs from it down through the spout in the sideof the oil saver and through the hose adjusted thereon back into thecasing of the well or into a tank, orsuch other receptacle asmay beprovided therefor. To adjust the oil saver around the tubing the sidesare forced together, the lock-link pushed up over the lock-arms and thetubing'is then unscrewed by means of pipe tongs. When not in use thelock-link is drawn back from the lock-arms and the sides are thrown outof the way.

The hinge-bolt screws into a clamp or saddle attached to the gas pipeleading out of the casing-head. There is an offset bend in thehingesbolt. By turning the hingebolt to the right or to the left in itsscrewsocket in the clamp or saddle the oil saver can be moved up to oraway from the tubing or it can be opened up and moved back out of theway. I am aware that the idea of an oil saver is not new ;but claim thatthe combination with the oil saver of the lockarms, hinge-arms, andhinge-bolt with oii'-set bend, adjusted in saddle or clamp on the gaspipe leading out of the easing-head is a patentable invention.

The combination herein described is shown in the accompanying drawings.

I claim as new and desire to secure -by-Lettei's Patent A tubingoil-saver having two semi-cylindrical sides; each side having ahinge-arm lock-link bein adusted in a hook on one ot the LOCk-ELIDJS;the ends oi the h nge-arms being hinged together and; restmg on a 1,esaose saver with hose attachment, substantially as described. y

In testimony whereof- I have signed this specification in the presenceof two subscribing witnesses, this 19th day of J 11ly,' 1921.
